Formula: sin(θ) = b / a

The value of sin(θ) ranges from 0 to 1, representing the proportion of the vertical side to the horizontal side. A higher value indicates a more elongated ellipse.

Cosine Function

The cosine function of an ellipse in the first quadrant determines the ratio between the length of the horizontal side and the length of the major axis of the ellipse. It is denoted as cos(θ).

Formula: cos(θ) = a / c

Here, a is the length of the semi-major axis, and c is the distance from the center of the ellipse to a focus. The value of cos(θ) ranges from 0 to 1, representing the proportion of the horizontal side to the major axis. A higher value indicates a flatter ellipse with a shorter major axis.

Tangent Function

The tangent function of an ellipse in the first quadrant determines the ratio between the length of the vertical side and the length of the horizontal side of the ellipse. It is denoted as tan(θ).

Formula: tan(θ) = b / a

The value of tan(θ) ranges from 0 to infinity, representing the steepness of the ellipse. A higher value indicates a steeper curve, whereas a value close to 0 indicates a nearly flat ellipse.

Cosecant Function

The cosecant function of an ellipse in the first quadrant determines the reciprocal of the sine function. It is denoted as csc(θ).

Formula: csc(θ) = 1 / sin(θ)

The value of csc(θ) ranges from 1 to infinity. It represents the proportion of the horizontal side to the vertical side. A higher value indicates a more compressed ellipse.

Secant Function

The secant function of an ellipse in the first quadrant determines the reciprocal of the cosine function. It is denoted as sec(θ).

Formula: sec(θ) = 1 / cos(θ)

Similar to the cosecant function, the value of sec(θ) ranges from 1 to infinity. It represents the proportion of the major axis to the horizontal side of the ellipse. A higher value indicates a longer major axis.

Cotangent Function

The cotangent function of an ellipse in the first quadrant determines the reciprocal of the tangent function. It is denoted as cot(θ).

Formula: cot(θ) = 1 / tan(θ)

Like the cosecant and secant functions, the value of cot(θ) ranges from 1 to infinity. It represents the steepness of the ellipse but in the reciprocal form. A higher value signifies a flatter curve.

In the study of triangles and trigonometry, we consider the unit circle which, by definition is an ellipse of eccentricity zero. What happens to the trigonometric functions when the eccentricity is different from zero? This short booklet provides an extracted cheat sheet version of the answer to this question.
Trigonometric functions, including the calculation of the arc length of an ellipse are presented for ellipses for any generic ellipse or a specific ellipse called the Unit Ellipse having its' minor-semi axis equal to [a=1] and its major-semi axis [sqrt 2], calculated for any given angle, between 0°-90°, for the radius being a function of the given angle.
This short booklet is the version to the subject matter until the release of the complete book with theory and proof.
